I have endometriosis and lately my periods have been really heavy. This last period lasted for 7 days (I am normally 4-5 days max) and it has been coming every three weeks 9I was regularly 28 day cycles). I had extreme cramping that left me unable to function or move for an entire week. I took pain meds but nothing was able to get to thepain. It felt like contractions. I have my tubes tied. Now I am having the cramps (1 week after my period) and noticed small amounts of blood in my stool. Any advice or suggestions would be helpful.
